Soft Tissue Ultrasound

What is Soft Tissue Ultrasound?
Soft tissue ultrasound is a non-invasive method for the diagnosis and evaluation of various conditions and diseases of the body's soft tissues, such as muscles, ligaments, tendons, subcutaneous adipose tissue, and skin. This method can be supplemented with the Color Doppler ultrasound function, which allows the clinician performing the clinical assessment to also conduct a comprehensive analysis of the vascularization of the examined organs and detect the presence of any lesions. Ultrasound examination is usually prescribed to analyze benign reactive or inflammatory lymph nodes, as well as neoplastic ones. This medical examination method is also used to detect and diagnose inguinal, abdominal, scrotal, and umbilical hernias. In most cases, the physician prescribes soft tissue ultrasound when an unspecified mass is detected. A typical case, for example, is superficial lipomas, benign formations that tend to form in adipose tissue and require surgical removal. Additionally, ultrasound-guided needle biopsy can be performed. Doctors also use ultrasound to monitor the healing process of postoperative sutures, phlegmons, and abscesses.
Types of Soft Tissue Ultrasound
Below are some of the most common types of ultrasound diagnostics:
Ultrasound of the Skin and Subcutaneous Tissue
Physicians routinely encounter skin and soft tissue infections, as well as foreign bodies. Ultrasound provides detailed images of the subcutaneous and submucosal tissue and is an extremely useful tool for the rapid assessment of these common problems. Furthermore, ultrasound is informative for detecting any skin anomalies (e.g., tumors), as well as subcutaneous edema and necrotizing fasciitis — which is often associated with a preceding injury (e.g., an open wound, an insect bite), and represents a rare, rapidly progressing, and life-threatening infection affecting the subcutaneous tissue, fascia, and surrounding soft tissue structures, including muscles.
Joint Ultrasound
Ultrasound examination is prescribed for injuries, pain, swelling, and redness in the joint area. Ultrasound helps to detect inflammatory or degenerative changes of the joint capsule and its ligaments, to assess the state of the cartilaginous surfaces, and to determine the presence of effusion (fluid) within the capsule.
Ultrasound of Muscles and Tendons, Fascia, and Ligaments
Ultrasound imaging uses sound waves to obtain images of muscles, tendons, ligaments, and joints throughout the body. It is informative, for example, for the diagnosis of strains and fractures. It allows for the detection of injuries with ligament damage, as well as inflammatory processes.
Ultrasound of Soft Tissues of the Head and Neck
This is a valuable method for the assessment of soft structures of the head and neck, such as muscles, salivary glands, and blood vessels. Ultrasound can help diagnose conditions such as tumors, infections, or blockage of blood vessels.
Ultrasound of the Inguinal Region
This is an imaging procedure targeting the area between the abdomen and the upper thigh. It is primarily used to examine the muscles, soft tissues, and to detect common problems such as hernias (inguinal or femoral), lumps, or injuries.
Ultrasound of Lymph Nodes
This is an examination method that allows for a detailed view of the structural abnormalities of the lymph nodes, including their shape and size. The diagnosis helps the physician monitor the treatment of long-standing and poorly manageable chronic diseases, such as lymphadenitis or tonsillitis, and based on the characteristic signs of altered lymph nodes, to suspect oncopathology.
Soft Tissue Ultrasound for Sarcoma Diagnosis
Ultrasound is highly informative for the diagnosis of soft tissue sarcoma — a form of tumor affecting muscles, connective tissues, adipose tissue, ligaments, blood and lymph vessels, and nerves. Soft tissue sarcomas can develop both superficially and deeply. They are often asymptomatic, but among the most typical symptoms is a painless swelling. For diagnosis, physicians first use soft tissue ultrasound and then, if abnormal masses are detected, they conduct additional examinations.
How Soft Tissue Ultrasound is Performed
Soft tissue ultrasound is a non-invasive medical procedure that uses high-frequency sound waves to create images of the body's structures. The patient lies on a couch, and the doctor will advise them on how to position themselves depending on the area of the body being examined. It may be necessary to change position during the examination. A special gel is applied to the area to be examined. It helps the transducer (the device that emits and receives sound waves) to slide easily and ensures direct contact with the skin, eliminating air pockets that can interfere with the sound waves. Then the doctor moves the transducer over the area under investigation. This device emits sound waves that reach the body and reflect back upon encountering an obstacle (e.g., an organ or tissue). These reflected waves are converted into images that are displayed in real-time on the monitor. During the procedure, images can be captured for subsequent analysis. After the ultrasound is completed, the gel is removed from the patient's skin. The specialist then provides a conclusion.
How to Prepare
As a rule, no special preparation is required for most types of soft tissue ultrasound. However, depending on the area to be examined, the patient may be asked to remove hair from the corresponding zone. It is also recommended to bring the results of previous ultrasound and other examinations that led to the consultation. This will help the doctor establish a clearer and more complete diagnostic picture.
What Can Replace Soft Tissue Ultrasound?
There are no alternative diagnostic procedures that are accessible and provide the same information as ultrasound. In case of doubt regarding the nature of the lesions discovered during the ultrasound examination, the physician may prescribe additional instrumental examinations, such as Computed Tomography (CT) and/or Magnetic Resonance Imaging (MRI). Ultrasound of the skin, subcutaneous tissue, and soft tissues is a diagnostic method that allows for the real-time visualization of soft tissue structures and aids physicians in making an accurate diagnosis and selecting the optimal treatment strategy.
